Direct Known Subclasses:

QualifiedCertificateFactory

public class CertificateFactory

extends CertificateFactorySpi

This class implements a CertificateFactory for X.509.

Certificate Factories are used for reading encoded certificates and Certificate Recovation Lists (CRLs) from input streams.

For instantiating the IAIK certificate factory call the getInstance factory method of the java.security.cert.CertificateFactory engine class, thereby supplying the certificate type ("X.509") and the name of the IAIK provider:

 CertifiacteFactory certFactory =
		CertificateFactory.getInstance("X.509", "IAIK");
 

Subsequently use the generateCertificate, generateCertificates, generateCRL, or generateCRLs method for pasrsing a X.509 certificate, a collection of X.509 certificates, a X.509 CRL, or a collection of X.509 CRLs, respectively, e.g.:

 Collection c = certFactory.generateCertificates(is);

Method Detail

engineGenerateCertificate

public Certificate engineGenerateCertificate(InputStream is)
                                      throws CertificateException

Parses a X.509 certificate from the supplied input stream.

Overrides:

engineGenerateCertificate in class CertificateFactorySpi

Parameters:

is - the input stream supplying the encoded certificate

Returns:

the X509Certificate parsed from the stream

Throws:

CertificateException - if an decoding/parsing error occurs

Returns:

the collection of X509Certificates parsed from the stream

Throws:

CertificateException - if an decoding/parsing error occurs

engineGenerateCRL

public CRL engineGenerateCRL(InputStream is)
                      throws CRLException

Parses a X.509 CRL from the supplied input stream.

Overrides:

engineGenerateCRL in class CertificateFactorySpi

CRLException - if an decoding/parsing error occurs

engineGenerateCRLs

public Collection engineGenerateCRLs(InputStream is)
                              throws CRLException

Parses a collection of X.509 CRLs from the supplied input stream. The collection may be supplied in one of the following formats (encoding = DER):

1. PKCS7CRLList
2. Chain of DER encoded X.509 CRLs

Overrides:
